What a pile of steaming horse manure!
No-one comes out of that smelling very good and in that I specifically include the coroner who seems to have a bad case of the cultural cringe. Obviously hick local instructors would have no hope of teaching a man of quicksilver intellect, oh and problems in the approach and landing phase are obviously irrelevant to circuits that by witness accounts were 1, hammerheaded - go around, 2. too fast - go around, 3. crowded self behind another aircraft, stalled and spun on base to final turn.
As for moving batteries and chucking lead in the tail ("he had trouble getting the tail up initially and thought the aircraft needed more weight in the tail to help it"
all without the benefit of a proper, documented weight and balance.....
